The Derry Bold Thermostatic Radiator Valve and Lockshield set in Silver is designed for homeowners and installers seeking a refined, modern finish for vertical pipework heating systems. This set provides high-precision temperature control and durable construction, making it an excellent choice for optimizing energy efficiency in standard UK water heating setups. A key caveat to note is that this specific model is designed for straight installations, so it is essential to confirm that your radiator pipework orientation matches this configuration before starting the installation process.

No, this is a straight valve set designed specifically for vertical pipework. Using it on angled pipes will cause alignment issues.
Yes, the kit includes both the thermostatic head and a matching lockshield to ensure your radiator has a uniform look.
It is designed for 15mm pipework but includes 8mm reducers for versatility.
The head contains a heat-sensitive element that expands or contracts to automatically adjust the flow of hot water into the radiator based on the room's ambient temperature.
It is designed for standard UK water-based central heating systems. If you have a highly specialized or industrial system, consult a professional plumber.
Ensure the system has been correctly bled of trapped air and that the thermostatic head is properly clicked into position.
Check that the valve head is not obstructed by curtains or furniture, as this interferes with the sensor's ability to read the ambient temperature.
Ensure that a high-quality jointing compound or PTFE tape was used during installation and check that the compression nut is tightened correctly.
Installation of the Derry Bold set requires draining the heating system, so it is recommended to have a professional plumber perform the work unless you are experienced with domestic heating systems. Ensure that your pipework is correctly aligned for a straight valve connection.
